Pau can't sign for much more if he starts this year at 3 mill. They don't let someone come for a year and then have bird rights after that.

I don't thing a trade excludes doing something of free agency. If you think moving amare for nothing is possible then you should understand that moving Larry sanders and illyasova is just as possible in a year if getting Marc gasol was really worth losing sanders, illyasova and bargnani
